Title: Hand-held power-operated shears
Inventor: WELLS ANDREW J
IPC: B26B15/00
Filed: 1991-03-25
Granted: 1998-06-09
Abstract: A   hand-held    fluid    power-operated    shears characterized by a body including a pistol grip handle portion,  a  blade-receiving  recess  and  a  cylindrical cavity with a removable cover over the blade-receiving recess.  One of a variety of different size and design pairs of interchangeable shear blades may be installed in the blade-receiving recess.  The blades are pivotally connected  and  each  has  a  forward  cutting  section projecting  forwardly of  the  housing  and  a  rearward extension,  the extensions being removably received in the blade-receiving recess to hold one blade fixed while permitting relative movement of the other.  One end of a piston  rod  is  fixed  to  a  piston  provided  in  the cylindrical cavity for reciprocal movement therein.  The other end of the piston rod is  in  direct detachable engagement with the rearward end of the extension of the relatively movable shear blade.  Fluid flow passages are provided within the body, being adapted for connection to a source of fluid under pressure and in communication with the cylindrical cavity on opposite sides of the piston for introduction of fluid thereto and exhaust fluid  therefrom.     Valve  means  are  provided  for controlling flow of fluid through  the shears.   Power trigger means which are operable from the pistol grip handle are provided to actuate the control valve means and safety trigger means are provided operable from the pistol grip handle to prevent accidental operation of the power trigger.

Title: Control signal initiator responsive to a hinge position
Inventor: MISCHENKO NICHOLAS
IPC: H04W88/02
Filed: 1992-03-13
Granted: 1995-03-14
Abstract: A hinge actuated switch apparatus initiates a control signal responsive to the rotational movement of a flip element (103) on a radiotelephone unit (100). The radiotelephone unit's circuitry senses of whether the flip element (103) is in a closed or open position. The integrated miniature switch comprises a pin (223) attached eccentrically to one end of a hinge (221) on the flip ele-ment (103). As the flip element (103) is rotated, the pin (223) drives a push rod (203) to compress a conductive elastomeric pad (205) thereby electrically connecting normally open conductive circuit pads (234 and 236), on the surface of a printed circuit board (201).

Patent CA-2091332-C (CA)
Title: Semiconductor non-volatile memory with tunnel oxide
Inventor: WALKER ANDREW JAN
IPC: H01L21/8247
Filed: 1993-03-09
Granted: 2002-01-29
Abstract: Very thin tunnel oxides are used in conventional non-volatile memories to obtain a sufficiently strong tunnelling current to or from the floating gate.  Usual thicknesses of the tunnel oxide lie in the 8-10 nm range. The invention renders it possible to use tunnel oxides of a much greater thickness, for example of the order of 20 nm, for comparable tunnelling current values.  According to the invention, the tunnelling effect is enhanced by implantation of a heavy, high-energy ion, for example As, into a comparatively thin poly layer of the oxide. During this, Si atoms are propelled from the polylayer into the oxide, so that the oxide is enriched with Si, which causes a major change in the tunnelling characteristics. The same oxide which functions as a gate oxide elsewhere may be used for the tunnel oxide. An important advantage of the invention is that direct contact between the tunnel oxide and photoresist layers necessary during the process is avoided, so that the properties of the tunnel oxide are not or at least substantially not impaired by the photoresist.

Granted: 1999-03-23
Abstract: Optoelectronic devices such as photodetectors, modulators and lasers with improved optical properties are provided with an atomically smooth transition between the buried conductive layer and quantum-well-diode-containing intrinsic region of a p-i-n structure. The buried conductive layer is grown on an underlying substrate utilizing a surfactant-assisted growth technique. The dopant and dopant concentration are selected, as a function of the thickness of the conductive layer to be formed, so that a surface impurity concentration of from 0.1 to 1 monolayer of dopant atoms is provided. The presence of the impurities promotes atomic ordering at the interface between the conductive layer and the intrinsic region, and subsequently results in sharp barriers between the alternating layers comprising the quantum-well-diodes of the intrinsic layer.
